Abstract: The invention introduces a cellular air bag insulator and its uses in insulating a house window, a house door, a house wall and process equipment, such as an evaporator, a refrigerator and a distillation column. A cellular air bag insulator is a light weight insulator and comprises an outer enclosed bag and an expansible and collapsible multicompartment core such as a honeycomb structure joined to the outer bag. It can easily be inflated and deflated. When it is inflated, multitude of horizontal air compartments in multilayers are formed in the bag to provide a high resistance to heat transfer through the bag by reducing convective flow of air within the bag and by requiring the heat to pass through the multilayers of air compartments. When it is deflated, it occupies a rather small volume and can be rolled up or folded into a compact form that is convenient to handle and store.

Abstract: Pneumatic structural and cushioning material of plastic sheets, bands, and/or tubes, which are compartmentized into a plurality of chambers. The material is capable of convenient and economical storage and shipment in a collapsed state and rapid inflation to an operative state at the point of use. The chambers embody one-way valving arrangements to maintain the chambers in an expanded state over long periods of time, rendering the product useful in cushioning loads during shipment by land, air or water; in safety devices for humans in vehicle bumpers, air cushions, and buoyant devices of all types; and in structural assemblies of either temporary or permanent types to attain heat and sound insulation effects.

Abstract: A molded game ball, particularly for volley-ball, hand ball and soccer is made by winding a layer of fibrous material on an inflated rubber bladder, applying a sheet of a rubber mixture with a vulcanizing agent on this layer, imprinting in a cold mold a network of fields on this layer indicating places where cover segments have to be bonded thereon so that do not get in touch one with another on their periphery and by finally pressing this semiproduct with bonded cover segments in a smooth mold at temperatures for vulcanizing.

Abstract: An improved method for forming a strip material and subsequently inflating and sealing the strip material at the site of its intended use to form cushioning material. Two heat sealable films are fused together in discrete areas to form two rows of inflatable chambers along the strip and a passageway extending the length of the strip material between the rows, with each of the chambers having an inlet opening narrower than the main portion of the chamber communicating with the passageway. The strip material is shipped uninflated to the site where the cushioning material is to be used. The strip material is then inflated by propelling the passageway in the strip over an air nozzle to inflate the chambers through their inlet openings, and the inlet openings are then sealed after the films are first pressed together and tensioned around the area to be sealed to both insure a wrinkle free seal and insure that air pressure in the chamber will not rupture the sealed area while it is hot.

Abstract: A system of providing convenient filling and sealing of air cushions at the site of their intended use, such as at a packaging line. A concatenation of inflatable cushions is prepared with each cushion comprising two thin films of a thermoplastic, at least one of which films has a generally central opening. The films are fused together in discrete areas to define a plurality of inflatable chambers between the films disposed around the opening, with each of the chambers having an inlet passageway communicating with the opening. The cushions are shipped uninflated to the site where they are to be used, and are then inflated and sealed on a device which includes a nozzle for simultaneously directing air through the opening of the cushion and the inlet passageways to inflate the chambers, and a means for sealing together the films in a small area around the opening to close the inlet passageways to the chambers.

Abstract: A moulding apparatus including a pair of mould cavities with locking spue grooves, means to form moulded rubber article parts in the cavities, means to prework the rubber without substantial curing before it is formed, means to pressurize the mould with gas and means to bring the mould cavities together to join the article parts. The arrangement for pressurizing the mould includes a retractable casing which is movable between a position in which the mould cavities are enclosed to permit their pressurization and a position in which the cavities are accessible outside the casing.

Abstract: An improved system and a device for providing air inflated cushioning material which is filled and sealed at the site of its intended use, such as at a packaging line. Included is an elongate flexible layered strip material comprising two heat sealable films fused together in discrete areas to form two rows of inflatable chambers along the strip and a passageway extending the length of the strip between the rows, with each of the chambers having an inlet opening narrower than the main portion of the chamber communicating with the passageway. The strip is shipped uninflated to the site where the cushioning material is to be used, and is then inflated on the device through which the passageway in the strip is propelled over an air nozzle to inflate the chambers through their inlet openings.

Abstract: A system providing an improved inflatable cushion of the type comprising two films of a thermoplastic fused together to provide a plurality of inflatable chambers between the films, with each chamber communicating with a central inlet opening through an inlet passageway; and an improved device for filling and sealing such a cushion. The inlet opening for the cushion extends through only one of the films, and the device has a nozzle which directs air into the opening against the portion of the other film which extends across the opening, so that the air will be evenly deflected through the inlet passageways to simultaneously inflate all the chambers in the cushion.
